Muhammad bin Abu Mujalid narrates: Abdullah bin Shaddad and Abu Burdah sent me, and both of them said to me: Go to Sayyiduna Abdullah bin Abu Awfa (may Allah be pleased with him) and say to him: Abdullah bin Shaddad and Abu Burdah send you greetings of peace, and both of them have said: Did you people use to conduct Salam (advance payment) transactions in wheat, barley, and raisins? He replied: Yes, during the blessed time of the Prophet (peace be upon him), we used to receive spoils of war, so we used to conduct Salam transactions in wheat, barley, dates, and raisins. I asked: Did you do it with the person who owned fields or with the one who did not own fields? He replied: We did not investigate about this. (i.e., we used to conduct Salam transactions with both types of people)
